COMBINATION 'nvrrnmiiivmf Y Application led May 12,V

This invention relates to a combination implement, and the primary objectl of this invention is to provide in a unitary structure different instruments such as calipers, square 5 protractor and rule.

A still further object of the invention is to provide an instrument of the character described, which can be cheaply manufactured, used as an advertising medium, and

m which will also be thoroughly reliable and et'cient in use for the purposes indicated.

Other objects andadvantages of the invention will become apparent from a study of the following description, taken in connection with the accompanying drawings where- 1n: Y Y

Figure ,l is a plan view of the implement in positionfor use as a rule.

Figure 2 is a plan View of the device with the legs `thereof disposed in vparallel contacting relation.

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 2.

Figur-e 4 is `aplan view of one of the legs of the device. Y

Figure 5 is a similar view of the other leg of the device.

Figure 6 is a plan View of a pointer car-v rying disk.

Figure 7 is a sectional view taken 'substantially on the line 7-7 of Figure 4. o With reference more in detail to the drawings, it will be seen that 5 indicates the legs of the device, each of which at one end, is y'provided with a longitudinal relatively nar row extension to provide a divider point 6 terminating at its free end with an inwardly directed lateral extension forming a caliper point 7 Each of the legs 5 at its inner end is provided with a slightly offset disk 8, and these disks are arranged in overlapping relation. One of the disks is provided with an aperture 9 for accommodating a hub 10 formed on the other of said disks whereby to provide a pivotal connection between the legs at said inner end of the legs. l

The disks provided with the aperture 9 is coniined on the disk provided with the hub 10 between the-last referred to disk, and a fsm. semina. ystessa;

circulan'platel'llll'j i .tirely through theV plate 11 and the 10 thus providingfor anIeiicientfjoiiitQy j On correspond'fngfacesofl the legs I provide a scale fractionsth'ereovf, the' scale continuing Valongv correspondingfa'ces of the'y points 6'. 14 denotes a circular scale on t-he apertured disk 8. The scale 14 is suitably 'graduated and .i

cooperates with the scale 15 provided onthe @Q disk 8 provided with thel aperture 9.

The plate 11 has radiating therefrom a circularseries of pointers 16 adapted to be read against the scales 14 and 15 whereby the points may be accurately set at any desired distance apart when using the device as calipers. The plate 11 is held inposition through the medium of a set screw 17 extending therethrough "and engageable with an aperture therefor provided eccentrically in 70l the hub 10. l

The plate 11 and pointers 16 are preferably formed of metal orother suitable resilientmaterial, and the vspace between 'thehub carrying disk and the pointer 16 is such, 75 that the pointers 16 will frictionally bear against ,the apertured` disk f8 for V yieldably retaining the disks against relative rotative movement. .Y

The many uses to which la combined i1n.V BQ plement of this character maybe used' is thought j apparent `from the foregoing description, .taken in connectionwith the ac1` companying drawings and VVaccordingly a more detailed description thereof is thought 3,5.

unnecessary.

Eventhough I have herein shown and de'- scribed the preferred embodiment of the invention, it is to be understood thatthe same is susceptible of changes, modifications' and 90 improvements coming within` the scope of th appended claims.

Having thus described inventiomwhat n i l I claim as new is: 1. An. implement fof scribed comprising a pair offlegs provided at corresponding ends with disks, one of said disks provided with a hub, and the other of said disks provided with an aperture through which said hub eXtends, one of said disks'w0 nijs graduated ,wineries and 55.,

the character de-` 5 said scales.

being provided with an annular caliper scale, and a-plate on said disk and rotatable relative thereto, and radial pointers carried: by said plate* yand adapted to be read against 2. :In a device Y'ofthe lclass described, a leg having, one e'ndrportion thereof 4forxnedfwith Y, Va disc having a centrally located iipstandingv Y hub,' a second leghaving al disc overlying 'l 10 Said yfirst named disc and being provided i Q withV a centrally located aperture reoeiving n' said hub, a plate secured at spaeed points to said hub and overlying vthe secondnamed disc 'and having frictional contactjtherewith said Y v1*15,second-named disc being provided `with' an annular scale; said plate' being provided"withy V i a 'plurality Vof radial pointers "cooperatingy with said'scale vto indicatethe positions voff` the legs Vwith respectv tofeach other.
